Relay remote commands

If the switches 'S1', 'S2' are available on the power print and set to "OUT", then two relay outputs can be operated via the heat meter. If
the function programming of the relay ("OUTPUTS" / "FCT") is set to "M-Bus", then these can be switched on or off via the remote com-
mands (MBus or LON):
NviSetRelais1
NviSetRelais2

Network variables

®
With LONWORKS networks, nodes communicate their measured values and parameters using Standard Network Variables (SNVs) to oth-
er network nodes of the same network. If they are changed by node-specific firmware, the operating system of Neuron automatically adopts
the communication of the new value via the network. Which of the communication connections of the system are carried out is determined
in "binding" (no further details are available here).
®
CALEC ST only uses variables with Standard Network Variable types (SNVT Master list Version: 10.00), to ensure binding without prob-
lems.
The network variables are subdivided into logical groups. These groups are designated objects. In CALEC
Information", which provides more detailed information about all the nodes using the heat meter-specific profile 'Utility Data Logger Reg-
ister #2110' "Current Values" for the current meter status; "Memory 1" for the memory 1 values and "Freeze Memory" for the frozen me-
ter readings. In addition 'Open-Loop Sensor Object #1' "Instant Values" provides information on the actual values (temperatures, power,
flowrate and density), and the 'Open-Loop Actuator Object #3' "Relay 1" and "Relay 2" for control of the relays.

Memory values

® ®
The CALEC ST as LONWORKS
Along with the current data, a total of two memory data sets are available. These are:
• The preset day values for Memory 1 in profile: 'Utility Data Logger Register #2110': "Memory 1"
• The freeze data (frozen values) in profile: 'Utility Data Logger Register #2110': "Freeze Data".
